Lady Gaga reportedly splits from manager Troy Carter

The pair have worked together since 2007, when Carter was recruited by her record label, according to The Hollywood Reporter. He has since become a big-name speaker for music industry events.

Carter often described their working relationship as a balance between creative and business decisions – Gaga would handle 95 per cent of the creative side of things and he would handle 95 per cent of the business decisions. The strategy has led to Gaga selling over 20 million albums worldwide.

"She was very specific about her vision, all of the music was there, and all she needed was someone to help her translate it to the rest of the world, which is where I came in," he said of their initial meeting in a recent interview.

Other names currently on Carter's management roster include John Legend, violinist Lindsey Stirling and US boyband Mindless Behavior. His Atom Factory Records label recently signed a deal with Capitol Music Group.

Lady Gaga's publicist declining to comment on the reports when approached by NME.

Gaga's new album 'ARTPOP' will be released on November 11. A string of tracks including the piano-led, Rick Rubin-produced ballad 'Dope', 'Mary Jane Holland', the R Kelly collaboration 'Do What U Want' and singles 'Applause' and Venus' have already been revealed by the singer.
